Description

Issue by ktoso Monday Sep 28, 2015 at 08:31 GMT Originally opened as https://github.com/akka/akka/issues/18576

As mentioned in https://github.com/akka/akka/issues/18571#issuecomment-143671349 we have decided to not port this feature in the initial round of porting features from Spray, however at some point we may want to re-visit this decision if given good reasons.

Why not support it right away: It would require bypassing the entire streaming infrastructure and we back-pressure guarantees along with it etc.

Current replacement API: For users who were using WriteFile support we recommend feeding the HttpResponse using the SynchronousFileSource.

Contributor guide

Research direction
Investigate the current streaming infrastructure and back pressure mechanisms in akka http to implement WriteFile/transferTo support while ensuring back pressure guarantees are maintained.
